Abstract

Une seringue hypodermique (10) comporte un cylindre (12), un plongeur (26) s'étendant dans le cylindre à travers un embout (22), et un piston (30) monté sur le plongeur à l'intérieur du cylindre. Le piston divise sélectivement le cylindre en deux compartiments (34 et 36) permettant le stockage de substances distinctes, le piston présentant une ouverture traversante (54) qui est soit fermée soit ouverte par le plongeur en fonction de la position de ce dernier par rapport au piston. Le plongeur comporte deux butées (66 et 77) permettant de commander le mouvement du piston par rapport au et avec le plongeur, ainsi qu'une troisième butée (76) destinée à entraver de manière libérable le mouvement du piston par rapport au plongeur. Ce dernier se verrouille mécaniquement à l'embout arrière pour provoquer le mouvement de l'embout avec le plongeur lors de l'utilisation de la seringue. Dans un mode de réalisation, la butée (77) au niveau de l'extrémité avant du plongeur est pointue de manière à faciliter l'assemblage du piston sur le plongeur.
